improvement of one version of Mono. Richard Simpson concluded that:
The version released by the mono team is really impressive. What impressed me the most about Mono is performance.
This version also has some improvements in debugging, especially USB debugging. Considering that cross-platform mobile development is a major use case of Mono, this improvement is
Mono 3.8 release: further performance improvement and scalability improvement, mono3.8
Mono 3.8.0 was released on September 10, September 4. The runtime of this version brings some performance and scalability improvements, and completes the migration to the Windows platform.

handshake, and the security token is expected to be included in the SYN message of the TFO optimization request.For the use of TFO. Here are some small warnings. The most notable of these is the lack of idempotent guarantees for data requested in the Initialized SYN message. Although TCP guarantees that repeated packets (which often occur repeatedly) are ignored by the recipient, this guarantee does not apply to the handshake process of the connection. The solution is now being standardized in
Reasonable Use of operator priority, performance optimization and improvement details, and operator performance optimization
In JAVA programs, most of the reason for performance problems is not the JAVA language, but the program itself. Developing good coding habits is very important and can significantly improve prog
From the previous user management system we will find that JSP is mainly to do the interface, but the use of JSP to authenticate users and paging processing, and servlet processing page is the quickest and most convenient, so the user Management system framework has been improved, the use of MVC mode.MVC is a design pattern that makes it mandatory to separate the input, processing, and output of an application. Using an
Some input items in the form are fixed and do not change the verification rules, such as the character length and required fields. But some of them are dynamic. For example, if the registered user name has such a check, you need to access the server background to solve this problem. This article will introduce how to use RemoteAttribute in MVC to solve this type of verification requirement, and analyze the deficiency of RemoteAttribute and the
At last month's PDC 09 conference, Jonathan Carter and Scott Hunter from the Microsoft ASP. NET team demonstrated some features designed for ASP. NET Versions later than 4. Their main direction was to simplify applications.ProgramDevelopment, support for web standards, and improve performance.
The ASP. NET team is considering the following features to simplify application development:

Avoid interacting with slower remote HDFS clusters, while data stored in Alluxio can easily be shared with upper-level components such as Flink, Zepp

MySQL replication has been around for many years since its launch, and its stability and reliability are also steadily improved. This is a process of continuous evolution. Because many important functions of MySQL depend on replication, the rapid development of replication is easy to understa
It is very important to improve the throughput performance of multi-core servers. Because servers are different from desktops and workstations, the channel for dealing with the outside world is the network. No matter what complicated computing operations the processor performs, the results must be returned to the request object through the NIC. In a sense, the NIC is the "throat" component of the server for external contact and communication. To some

The size and complexity of the page is the culprit for the performance problem, not the CDN. But this result also shows that relying on a CDN alone does not solve all the performance challenges.If deployed properly, a CDN is a very effectiv

Use the system-provided APIs whenever possible, because these APIs are compiled binaries that are highly efficient to perform. At the same time, some basic algorithm optimization, also can be used in JavaScript, such as the adjustment of the operation structure, here will not repeat.Because JavaScript is interpreted, it is generally not optimized for bytecode at ru
